12 SHEETS-SHEET l2- Fla E patented printing telegraph system referred to is practical and reliable, the use thereof necessitates a careful manufacture and accurate finishing thereof for the reason that any inaccura'cy in their make-up tends to clog the quick action of the selecting devices, making repairs necessary at times and the accurate finishing of the said enacting devices in the manufacture thereof pensive One of the objects of my present inven tion is to materially simplify the construction of the selecting devices for setting the printing wheel and the circuit or energy impulse controlled devices at the transmit tin end, angl to so improve the construction an arrangement pf the said cooperative devices, that the necessity of a close or exact finish and cooperative adjustment of the said parts is overcome, the selective and printing devices coiiperating with the printing wheel being especially so designed that inaccuracies of adjustment between the de- "ices on the transn'iitter, that control the dot and dash impulses, are automatically corrected, or in other words, the impulse length may he a little or much in excess of the wave required to shift the wheel with out in the slightest impairing the selecting devices or efl'ecting the desired set of the wheel,

In my patent above referred to, the two printing or type wheels and their constituent setof operating devices, are mounted. one upon each side of the printing point of the machine and the said wheels are indi vidually and alternately first shifted laterally in position with such point when set to their respective operative positions, after which the frame that carries the set wheel with its coacting devices, is a utomatically swung forwardly to cause the set wheel to print the selected character.

In my present construction of printing telegraph system the two type wheels have a fixed relation with respect to the printing devices, are closely held so their printing characters are separated by a single space and so the successive printing action of the two wheels prhduce two characters in a proper spared alincmcnt.

The two wheels in my pr sent system of printing telegraph are loosely mounted on a cgqntinuonsly rotating shaft operated hy a motor in action by the operator at the transmitter end when he desir s to send in the messag it being understood the motor continues in action until the transmitter operator manipulates the off key to cut it out.

in my present construction the two type wheels are held in frictional contact with the motor drive shaft and when released they re ate with the shaft, the release being efi'ecteo by the impulses sent from the transnutter, the dcgrec of rotation of the wheels being controlled by the selecting or stop devices At this point a wry essential feature of my present improxcmcm should he mcntinned, since the ame iclutes to the stop or selecting device that control the set of the type wli c-els, and in this connection it should he stated in my former patent lwrcinlwforc referred to, the stops with which the selecting or stop lingers court are arranged in an nular alinement and on the periphery of the selecting disk.

In the practical use of the aforesaid selecting disk liming the dot stops arranged and grouped w ith reference to the familiar characteristics of dot and dash symbols, it is necessary that the said stops he most accurately arrang d with respect to the means that actualcs the stop engaging or selecting lingcrs.arul unless a perfect correlative condi tion of the selecting linger actuating means and the said stops exist. under a rapid operation of the svstcn'n that is. the quick sending of the impulses that make up the clmractcr, the selecting devices at tunes, do not act with the desired degree of certainty.

In my present construction provision is made for overcoming the ohicctional feature mentioned by arrangu'ig the stops in such manner that the spaces between the stops are materially increased. the arrangement in the present case. showing four times the distance shown in my patented machine, and to provide for an accurate action of the dot and dash and stop fingers the several fingers are automatically shlftcd in position to engage the predetermin d ones of the stops on the type wheel, the said stops and the means for shifting the fingers in the present case being mounted directly on the face of the type wheel. The present case alsoembodies improved devices for printing the selected character the instant the type whccl is set and for immediately re leasing the said type wheel after printing to return to the normal position, and gencrally the printing devices include an electromagnct controlled impact or hummer head that strikes the paper against the character selected and electro-1nagnct controlled den :s that move the selecting lingers out of engagement with the set wheel, immedi ately after the printing hammers have been energized.

The two electro-magnet devices referred to. the printing and the release. are in the same circuit which is energized immediately the type. wheel is set. the armature travel of the printing and releasing magnets being differential, the printing armature closing in advance of the release armature.

It is understood there is a printing and a release magnet for each type wheel and in the present arrangement of my printingv particularly illustrates the frictional movement of the two type wheels. Fig. 17, is a transverse section on the line 17-17 on Fig. 14. Fig. 18, is a detail view of one of the type wheels and the selecting mechanisms, -'the wheel being at the normal or rest position.

Fig. 50 is a detail cross section taken on the line a a, on Fig. 50. i Fig. 51, is a detail view hereinafter referred to.

In describing the details of construction of the parts that constitute my present, printing teh'gra 'ih system, I shall take up, so far as possible, the various sub-mechanisms, in the order in which they come into action after the first impulse is sent from the transmitter, the detailed description of which will also hereinafter appear.

The type whet Z and selecting mechanism.- Referring now more particularly to Figs. 15 to 22, 66 designate the two type wheels and since each cooperates with an independent set of selecting devices, a detailed description of one type wl'ieel, and its 00- operating devices, will suflice for both. llheel (i has the symbols, signs, letters, characters, etc, such as usually employed inv the ordinary telegraphic codes and in the present caseit also has blank portions for the spac ing, paragraphing, on and off, impulses, from the sender, so no printing takes place when the aforesaid impulses are sent to the receiver. .Vheel 6 is loosely mounted on a shaft 5 but held in frictional contact therewith, the shaft having a'friction disk 50, against which the wheel is normally held by the coil spring 51, the frictional engagement of the wheel and shaft being such, that when released from any of the stop devices that hold the wheel from moven'icnt it will positively n.ove with the said shaft 5 which continually rotated, while the system is in action, through the. medium of the bevel gear 52, that meshes with a countcrshaft 33 that. carries a worm gear fi l held in mesh with a worm on the motor driven shaft 56. the several shafts referred to being mountedin a suitable framework, mounted on a main bed. in the manner clearly understood from the'drawings.

The character selecting mechanism that controls the set of the type is best shown in Figs. 18 to by reference to which it will be noticed the face of the disk has laterally projected lugs that form which. at prcdetennined times, the predetermined one of the selecting fingers engage, there living three of such fingers, the stop finger I. dot finger y and dish finger 2. In the present vshowing, the wheel (3 has as many stops as are chaitarters on the wheel rim. an

these are designated-S, the dot stops,

the stops with and S tho dosh stops To prov-lilo ampia time for the fingers 3 and z to dngiumk in position to engage with the said (in and dot amps; between the impulws from the sonrier, b the said sops; S-S' are arranged in a pin rnlii y of conoonm'ic rows, four being shown, it being unilazstooii that the number of web rows may e mars m l it also being door that {no grower in: inn: 1' of rows of gush 5!!)135, the greater the anoe mime-en he stops of cznzh row. i. pointing with the said rows oi iot and 1218i; stops are a mum her of ooi'icisntriorow of flanges 5?, that. form annular grmyscs 5, in which are lo rated the sficon l 21ml llllll' l rows of (kill stops, and the saiil flanges and gl'mn'es form the means for shifting the fingers: y and 2 in proper positim'l to engage with the respective rows of (lot and lush stops. it being obvious that since the fingers 7 and 2 are recipro dated lamrzilly in unison, no flung e5 or grooves for the dash stops are newieil.

The type \vlwel 6 hold to in; normal 112* turned position by the stop finger which, when the wheel rotm'es with the alizift to the normal point, drops into a long segment groove 63 in the outer edge of the whool and thus holds the wheel from turning with the shaft until it is again released in the mom nor presently explnineui.

In {no mechanism ilisolosed in 1} Film-n2: #7i2,939, before referred to the spam betwoon the dash stops with which ihho dash finger 2 counts, must be substantially mate! the length of the wiping contact as the transmitter end. iy reason of arranging the stops on the wheel in the manner bereinbeiore described, no such rototive adjustment between the. transmitter and the geiocting dash stops in my present system is rrquired, since the dibtance betweon each stop in each row of such siops is alike and positive, and hence the moment the. dash controlling disk" of the transmitter isenergized, the dash ship selecting linger picks up the required dash stop and holds the wheel, irrespective of the wiping or length of the dash impulse at the transs'nitter 'l arrangement of parts is very advantageous, since it effects much saving in the cost. of rnzumfacturo of the reoeiver, and does away "with much hand fitting and accurate correlative arrangement of the circuit breaker disks at the transmission and hereinafter fully explained) and the mien-ting mechanism Briefly outlined the operation of my pres ent priming telegraph is explained. as follows: in sending letter H, made by four shortimpulses, or don, from the transmitter, the. finger 3 is intermittently lifted (as hereinafter explained) four times, and like wise drops smooessively in line with. the secnnd, third and fourth rows of dot stops on the wheel, and selecting after its fourth lift the H siop which is in the fourth row oi stops on film wheel, Fig. 22. During the Successive four releases of the finger 3 filze type when], by reason of its frictional engagement with it's motor driven shaft, aims with the shaft. it being understood the said forward movement being four very quick succ, '9 mm cmems, and the degree of movement such that the character H on the wheel brought into the printing SitiOIL I The gelectng finger'x controlling 1 mach/1' ni8m.-Referring again more particularly to Figs. 18 to and to Fig. 42, it will be noted the fingers y, a, cooperate with a rock shaft 7, loosely journaled in bearing boxes F()- on the framing, and to the said shaft the dash finger z is fixedly held so it rocks with the shaft into or out of engagementwith the stops side of the type wheel. The stop and dot fingers ac-y have pendent shanks and they are hinged at the lower end, 1i sp. mg :0 normally engaging the stop finger to force it. inwardly. The upper ends" of the lingers w and 1 seat loosely in re-.

lecting position when the impulsc'is'set into the primary or main magnet. To prevent the dot linger being thrown back too far a yielding abutment 3 is located back of it, see Fig. 4'2. This yielding abutment is also limited in its forward thrust so that when the dot linger 3/ is normally positioned there is no spring pressure on it, and hence, it is freest to move laterally when engaged with one of the flanges, 10, 20 or 30.

The release and apply movements to the several fingers are effected by the primary or main line magnet l. M., there being one set of such magnets for each wheel and its coacting devices, the armature M forming a lever to which isconnected the lever rod 8, that has a bifurcated finger'BO, in which rides the crank pin of the rock shaft 7, it being clear from Fig. 18 that the variable impulses of Hie armature lever m control the movement of the selecting and stop fingers m-yz. The stop fingers a', it should be stated, doesnot shift laterally, but retains a fixed relation to the wheel face, it being in line to ride on the face of the said wheel and drop into the long segment groove (33 to engage the stop X that holds the wheel at the rest or normal position. The face of the type wheel has a long oblique flange 4 locatcd in adi'ance of .the first break oriseparation of the annular guide flanges, which, when the wheel is released and travels under the release action engages the dot finger y and shifts it together with the dash linger 2 back -to normal position, see Fig. 25.

Another and important advantage gained by arranging the" selecting lingers and the (lot and dasiistops on the type wheel as dcscribed and shown is, that the actual stepby-step moyement of the type wheel is posi tively controlled by the dot stops only, thus making an absolutelv accurate relation of the dash stops with the printing characters on the wheel unnecessary.

It will he noticed by reference to Figs. 15 and 17 of the drawings, the dot stops are arrzinged a little back of. that is,lag bohind the dash stops, and by reason thereof and further since the shaft Twhenthe in! pulse through the primary magnetis ended, is rocked to bring the dash finger away from the wheel face, and as the dot finger under such movement goes in the opposite direction and drops onto the face of the-- wheel, it comes into position to catch the dot lug that lags behind the dash lug that finished the selection of the character to be printed and holds the wheel to such posi tion, thus leaving the clot linger the only one to be released after printing.

By referring to Figs. 18 to 25 inclusive,

the operation of printing the letter H will be explained, the letter H, in the Morse telegraphic code, consists of four dots or four electric impulses sent in quick succession. \Vhen the type wheel 6 and its coacting stop, dot and dash fingers a, y, z, are at rest or at normal position, their relation is as shown in Fig. 18. Should it now be desired to transmit the letter H, the first electric impulse will energize the primary magnet PQM., draw armature M up,-thus rocking shaft 7 through the connec ti on 8, which shaft 7 when rocked (see arrow Fig. 42) will swing stop and dot fingers wg away from the face of the type wheel through the medium of their engagementwith the flattened portion of the recesses in which-they seat and also the pendent face 73 (Fig. 50) while the dash finger will swing inwardly toward the type wheel, this first aforesaid electric impulse having thus released the wheel 6 from the stop and dot fingers is free to rotate in the direction of the arrow (Fig. 18) until the first dot stop adjacent the cutout portion 1 strikes the dot' finger y, which in the meantime, together with the other two fingers, has assumed its original position, the first electric impulse having ceased, permitted such return, the parts being now positioned, as in Fig. 19.

'W'hen the second electric impulse is now sent in, the identical movement of the stop,

dot and dash fingers takes place again releasing wheel (5 for further rotation until the stop, adjacent cutout portion 2 strikes stop finger 3 said finger gradually moving in toward the center of the wheel, such inward movement being accomplished by the oblique guides 10-20-30, which engage the aforesaid finger 3 during the rotation of the type wheel and move the finger inwardly. The parts are now in position as in Fig. 20.

\'pe wheel and coacting fingers through the same cycle of operation, positioning the linger 7 against the dot stop adjacent the cutout portion 3, as in Fig. 21. The fourth electric impulse completes the sending of the character H and will position the linger- 1 as in Fig. 22. \Vhen the electric printing impu ses cease to come over the main line and the dog 111 (Fig. drops, it hair The third impulse carries the 2'?

and

Worm, until the character has been set to the printingpositi'on. For such purpose, I use a vibrating rod 117, loosely mounted on the outer end of the primary or main line magnet armature, and the said rod is guided in bearings 118 on the main frame so that its upper end engages the under side of the heel member 112, the lower end thereof resting on the armature, as shown. By the said ar rangement of parts it is obvious that the repeated impulses on the magnet vibrate the heel member 112, keep it up, and in consequenee holds the suit-ch 103 out of mesh with the worm and so soon as the sending impulses cease. the heel will drop and allow the switch hook member 114 to move into mesh with the worm 10;, and thereby carry the lever over to make contact with the mentber 108 to close in the circuit to the printing and the wheel releasing magnets, the lever remaining at the contact making position until the wheel has been released and returned to the normal position, and the cam 115 on the said wheel engages the lcxcr ill to move it up, the latter, when thus moved throws the switch 103 outwardly and holds it there.

It should be stated that while the printing and releasing magnets are simultaneously energized, the armature nun'clnlnts of the said magnets are so timed that the printing action occurs in advance of the relcas ing action.

The releasing of the wheel is elfected by a second notched rock shaft 181, the notch 18 of which receives the dot linger. the only linger that holds the wheel after the charm tcr is formed, the shaft 181 when rocked, acting as a cam to swing out the finger i/ and releases it from the type wheel. 'lhc shaft 1 1 is rocked by a rod lif that extends up from the armature 120 of the release magnet 131 and connected with a crank tin- ;gi-r ;.2 on the shaft 181, as will be clearly understood by referring to Figs. 23 to 2.3.

l'i/ wr' mirirq c mu! feed mm:lmm'snae-As cforc stat d, in my prcscnt machine. the paper carriage is moved after the tno wheels have cach printed a character, that is. after cal-l1 two characters are printed. and the de grco of nnncnient of the carriage being a double space movement. For returnin the varriago to normal, a single paragraphing magnet 125 is used, who e armature lever 12; carries a plunger rod U1 7 the up-movw mcnt of which sets in operation the drive gear for the carriage.

Referring now airticularly to Figs. 30 to 3 l, of the drawings, 5 9 designates a worm on the motor shaft and I23, a worm gear on a cross shaft 129 that has movement vertically with respect to the gear oil so that under the up-movcment of the plunger rod 127 it is thrown into mesh with the gear 5!) and when the impulse through the magnet I25 is broken and the rod l'ZT drops, it, the gear 128, drops out of connection with the motor shaft. In practice, the gear E28 is held in frictional contact with its shaft 120 so that should the paper carriage mechanism be hung up or the paragraphing magnet fail, the gear will slip on the shaft lit), and thercbv overcome dangrr of parts of the machine being broken or thrown out of opera the connection.

Shaft. 121i is mounted in a rock hearing 29 and thesaid shaft 129 has a cog gear 130 that normally discngage's the rack bar 131 of the carriage. it bring obvious that when the shaft 12$) is disengaged from the motor sha ft, during the operation of automatically flu-ding the carriage forwardly (see weight ll") while scnding characters, the gear 130 and shaft 129 rotate loosely hackwardly. hen the carriage is at the end of a line or" a new paragraph is to be started, and the "paragmplwr" has been operated, the said gear 130, by reason of its now being p0silively driven from the motor shaft, feeds the carriage hack quickly-to the place of hrginning. it being, obvious that the extent of the hack throw or movement depends on the length of the paragraph impulses.

'lhe carriage l l!) is ri-ici n'm-ably mounted on the flaming and in such manner that the paper is moved between the printing rim of the wheels and the printing hammer head and to facililatc the free movement of the carriage it is mounted on rollers lib-141 that ride upon the rail, or rack bar, as shown.
